Description

Technical Field

[0001] The present application relates to the field of construction vehicles, and more specifically, to a multifunctional construction vehicle with an asphalt mixing mechanism. Background Art

[0002] When paving an asphalt road or repairing a damaged asphalt road, the asphalt needs to be transported to the construction site by a transport vehicle for spreading and paving. In order to prevent the asphalt from cooling and solidifying during transportation, a stirring mechanism needs to be set up to stir it. The patent document with the prior art announcement number CN216891892U provides a multifunctional construction vehicle with an asphalt stirring mechanism. The device is provided with a rotating shaft to drive a stirring knife to rotate, so that the stirring knife can be driven by a driving motor to rotate through the rotating shaft, so that the rotating shaft can stir the asphalt inside the stirring tank, and then the stirred asphalt is discharged through the discharge port. A plurality of stirring knives are installed on the outside of the rotating shaft to stir the asphalt more fully.

[0003] In view of the above-mentioned related technologies, the inventor believes that since asphalt has a certain viscosity in a molten state, the spacing between two adjacent stirring blades makes it difficult for the asphalt in the spacing to be stirred, resulting in a poor stirring effect. Therefore, we propose a multifunctional construction vehicle with an asphalt stirring mechanism. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides a multifunctional construction vehicle with an asphalt mixing mechanism, which adopts the following technical solutions:

[0005] A multifunctional construction vehicle with an asphalt mixing mechanism comprises a transport body and a tail box, and also comprises a reciprocating screw rotatably installed on the upper inner part of the tail box and a motor fixedly installed on the outer side of the tail box, the motor is transmission-connected to the reciprocating screw, and a sliding sleeve is slidably fitted on the reciprocating screw, connecting plates are fixedly connected on both sides of the sliding sleeve, a plurality of stirring plates are eccentrically connected to the connecting plate, the upper ends of the stirring plates are slidably fitted with the connecting plates, a discharge trough is hinged at one end of the transport body, an adjusting rod is hinged on the discharge trough, the adjusting rod is slidably connected to the tail box, and a protrusion is transmission-connected to the motor, and the protrusion is used to drive the adjusting rod to move up and down.

[0006] By adopting the above technical solution, the motor drives the reciprocating screw to rotate, so that the sliding sleeve drives the connecting plate to reciprocate in the tail box. The stirring plate is inclined to the direction of travel, and the asphalt on the travel route can be scraped to both sides to prevent it from solidifying. Multiple stirring plates cooperate to effectively stir the asphalt in the tail box.

[0007] When the discharge trough is set at an angle, the motor drives the convex block to rotate, and the convex block cooperates with the adjusting rod to drive the discharge trough to shake, so that the asphalt is spread flat on the discharge trough and then spread on the ground, which can improve the spreading effect.

[0008] Optionally, a plurality of guide wheels are rotatably connected to the connecting plate, a guide rail is in rolling contact with the guide wheels, and the guide rail is fixedly connected to the tail box.

[0009] By adopting the above technical solution, the guide rail and the guide wheel cooperate to limit the connection plate, so that the sliding sleeve drives the connection plate to move horizontally when moving.

[0010] Optionally, the stirring plate is rotatably connected to the connecting plate, and one end of the stirring plate is fixedly connected to a limiting rod, and the limiting rod is slidably matched with an arc-shaped hole provided on the connecting plate.

[0011] By adopting the above technical solution, the limit rod is arranged at the end of the stirring plate with a smaller rotation radius, so that the side of the stirring plate with a larger rotation radius will generate force resistance when it comes into contact with the asphalt and will deflect. The limit rod cooperates with the arc hole to limit the angle of the deflection of the stirring plate, so that the stirring plate can be inclined with respect to the travel direction of the sleeve, thereby effectively pushing the asphalt on the travel path to both sides, thereby preventing the asphalt from solidifying.

[0012] Optionally, a fixing seat is fixedly connected to the tail box, the adjusting rod is slidably connected to the fixing seat, and a bolt is threadedly connected to the fixing seat, and one end of the bolt is abutted against the adjusting rod.

[0013] By adopting the above technical solution, when the bolt abuts against the adjusting rod, the discharge trough can be limited to prevent it from shaking, so as to facilitate its vertical and stable placement. When the bolt does not abut against the adjusting rod, the rotation of the protrusion can drive the adjusting rod to move up and down, thereby driving the discharge trough to shake, so that the discharge trough drives the asphalt to be flattened and evenly spread on the ground.

[0014] Optionally, a gear A is coaxially fixedly connected to one side of the protrusion, a gear B meshing with the gear A is fixedly connected to the motor output shaft, and a driving frame is fixedly connected to the adjusting rod, and the driving frame is in sliding contact with the protrusion.

[0015] By adopting the above technical solution, gear B drives gear A to rotate, and gear A drives the protrusion to rotate. When the protruding part of the protrusion contacts the driving frame, the driving frame rises, thereby causing the driving frame to reciprocate up and down, driving the discharge chute to shake.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. The reciprocating screw and the sliding sleeve drive the stirring plate to move back and forth in the tail box. The stirring plate deflects while passing, so that the asphalt on the route can be pushed to both sides to prevent the asphalt from solidifying. At the same time, the deflection caused by the resistance of the asphalt is non-directional, which can further improve the stirring effect of the asphalt.

[0018] 2. When the discharge trough is tilted, the convex block cooperates with the driving frame to make the discharge trough vibrate, so that the asphalt can be flattened on the discharge trough and then evenly spread on the ground, thereby improving practicality.

The upper end of the stirring plate 9 is slidably fitted with the connecting plate 6. A discharge chute 11 is hingedly connected to one end of the transport vehicle body 1. An adjusting rod 12 is hingedly connected to the discharge chute 11. The adjusting rod 12 is slidably connected to the tail box 2, and a protrusion 13 is connected to the motor 4 in a transmission manner. The protrusion 13 is used to drive the adjusting rod 12 to move up and down.

The stirring plate 9 is inclined to the direction of travel, and the asphalt on the travel route can be scraped to both sides to prevent it from solidifying. The plurality of stirring plates 9 cooperate to effectively stir the asphalt in the tail box 2.

[0027] When the discharge trough 11 is tilted, the motor 4 drives the protrusion 13 to rotate, and the protrusion 13 cooperates with the adjustment rod 12 to drive the discharge trough 11 to shake, so that the asphalt is spread flat on the discharge trough 11 and then spread on the ground, which can improve the spreading effect.

[0028] Reference Figure 1 A pump is fixedly installed at one end of the transport vehicle body 1, the input end of the pump is connected to the tail box 2, and the output end is arranged on the upper side of the discharge trough 11.

[0029] Reference Figure 2 A plurality of guide wheels 7 are rotatably connected to the connecting plate 6, and a guide rail 8 is in rolling contact with the guide wheel 7. The guide rail 8 is fixedly connected to the tail box 2. The guide rail 8 cooperates with the guide wheel 7 to limit the connecting plate 6, so that the sliding sleeve 5 drives the connecting plate 6 to move horizontally when it moves.

The limiting rod 10 cooperates with the arc hole to limit the angle of the deflection of the stirring plate 9, so that the stirring plate 9 can be inclined with respect to the travel direction of the sliding sleeve 5, thereby effectively pushing the asphalt on the travel path to both sides, thereby preventing the asphalt from solidifying.

When the bolt abuts against the adjusting rod 12, the discharge trough 11 can be limited to prevent it from shaking, so as to facilitate its vertical and stable placement. When the bolt does not abut against the adjusting rod 12, the rotation of the protrusion 13 can drive the adjusting rod 12 to move up and down, thereby driving the discharge trough 11 to shake, so that the discharge trough 11 drives the asphalt to be evenly spread on the ground after being flattened.

When the stirring plate 9 contacts the asphalt, it deflects, so that the asphalt on the travel path is pushed to both sides to prevent the asphalt in the tail box 2 from solidifying.
